Thread: Who is running a PEL500110 thermostat in their D2

I'm not up for trying to analyse the flow diagram in RAVE, but the text I copied in a few posts ago is directly from RAVE. 28/10, 2003hrs.

I have a spare t'stat and looking at it and my setup, 2000 V8.

Flow from short hose between alternator & a/c pump then tee piece which branches to top rad connection (inlet) or drops to t'stat OF THE BYPASS SPING BRANCH. This line is the top straight connection on the t'stat. The branch on an angle is the only one marked "to pump" and goes to pump inlet (underside of pump). Straight down goes to lower rad connection (outlet)through the thermostat controlled plate (which is in the bottom branch).

Now I'm not calling anyone anything but IF it was installed with the pump branch to the top hose (180degree rotation out) then the pump inlet flow from the radiator outlet would be forcing the bypass plate closed, take the easiest route which is back to the top hose (but has the pump flow through the engine against it (but the pump can't suck enough to provide flow)).

Sorry if it's a bit haphazard but typing on phone jn carpark, bonnet up in direct sunlight. If anyone in western Sydney wants to get together to compare and test stuff I'm always free to meet up. Be nice to get to the bottom of things andnot drag things through the mud because we're missing something obvious.

Hello,
Put a normal 88 degree back in what a hassle that was and now runs at 90 - 93 no problems. Was looking at a 82 degree hard spring but happy with what is in there now. with the light spring it would go up to 105 and at that point it was turn the car off and refit the old thermostat.

I have one in mine, no idea if it is hard or soft spring. However it runs about 6 deg cooler than the original. Coolant is at 84 deg when cruising, up to a max of 90 when I have to stop at lights etc. It is a V8, would have mentioned it earlier, but I thought everyone drove 8's :-)

Now 0325 and been staring at the fow charts for both TD5 & V8 for hours. There is a difference between the two and there may be some differences between detailed operation & the diagram. But if I go raiding for a spare t'stat now I'll get locked out.

Well ive discovered my problem,
having a good look at the inside of thermostat (PEL500110) I bought,
I can see on the rim of the thermostat itself (inside)
V2936 - 92deg C - 1203

are these PEL500110 in fact a 92deg C thermostat??

From what I read on here these are supposed to be 82deg C which is why I bought & fitted

Can Anyone else confirm the temp rating by checking theirs??

Can't see on RAVE what the op temps are supposed to be for K series freelander, but Ive seen several posts on the internet about freelanders boiling

I have no listing nor in any research have I found a reference to a 92deg t'stat. My 2 spares are both marked at 88.

The reference list I have posted is from researched info plus checks of operation I've made myself.

PEM100990 - Cream is 88° With hard Spring (Designed for Diesel and V8 applications)

PEM101020 - Black or Cream is 82° With Hard Spring (Designed for a V8 and used as a stopgap with K4 engines)

PEL500110 - Grey is 82° With Light Spring (K4 engines)

X2 Same as mine just had look now 92 deg C. How can they sell them as a 82 deg C ?????? I fitted the stranded hard spring much better today brought a new radiator went and warmed up the car didn't go above 93 deg C even sitting idling for a while at the lights.

Just checked RAVE, it says the thermostat for the TD5 starts to open at 82 degrees, fully open at 96 degrees. Fuel cooler opens at 82 degrees. Is the number on the thermostat the starting or fully open value? Bob
